Also historically no one has beaten the Celtics in the finals, but the lakers and 1958 St. Louis Hawks....

.
So they pretty much automatic when they get there.
Outside of the Lakers and Celtics no teams in the NBA have more than 6 championships. Right now the Bulls and Warriors are tied with 6. So lets see what happens...and whats more likely. The Celtics pass the Lakers with 18 championships or the Warriors being the first team outside of the Lakers and Celtics to win more than 6 rings.
